I try to be pretty strict. But theres times at the end of a set I'll hit few extra reps with a little help from Mo. Just enough to get an extra rep or 2. But not to the point I look like I'm trying to go under a limbo bar LOL

i like both ez and straight bar, for reverse curls for forearms i use an ez bar(preacher bench for real pain ) i do however agree that a straight bar hits the biceps better. It really is a double edged sword because with the ez bar in normal bicep curls i can lift more...due to other muscle involvement.

another point is grip width.. now a lot of people do not believe in isolation of a muscle but i think even a basic ex like barbell curls can be manipulated. sure a muscle is trained as a whole but a small movement, body position and grip can change it. it shifts more stress to an area of a muscle group...take close grip bicep curls...the outer head.. wide...the inner area...

Of course! I never understood people who claim that variety is useless since any exercise that works a muscle works the whole muscle.

Take a look at an anatomy chart that shows skeletal muscle and you'll see that, especially with bigger muscles like chest and back, many of those striations travel in different directions. It stands to reason, then, that movements through different planes will emphasize certain parts of a muscle over others.

The "all-or-nothing" principle is too simplistic to use here.

that was one of vince gironda 's axioms to train all aspects of the muscle.the great jcg advertised the ez curl bar back in the day. i heard at one time his biceps tendons were so beat all he could do was lat machine curls laying across a bench.
